In a surprise move, Apple has introduced a new programming language called Swift. It is compatible with Apple’s native Cocoa and CocoaTouch programming APIs.
Swift, which can be used to develop apps for both iOS and OS X devices, has already been released by the company in the beta version of Xcode 6, which you can download today, but will not officially be supported by those devices until both iOS 8 and OS X Yosemite are released this fall.
Notably, Apple has said that it can work “along side” Objective-C in projects — though no doubt the company hopes developers will in time fully adopt it, tying their work to its platforms. The upside, as with its new Metal graphics technology, is faster performance for apps, Apple says.
